Why can't Windows 7 install see my new SATA drive?

To install the RAID driver during the Windows install you need to have the driver on a CD or USB drive. When you reach the hard drive list option it will be empty, there is a button to load drivers. Choose this option and then insert the cd/usb drive and locate the driver. If all works properly, you will then be able to see the drive and install Windows 7 on it.
